Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, and in particular to a phase separation heat exchange device and heat exchange method. Background Technology

[0002] With the development of aerospace, chip cooling, fuel cells, and high-power electronic devices, the demand for heat dissipation is rapidly increasing. Although traditional microchannel heat exchangers can improve heat transfer efficiency, they often dry out due to gas phase accumulation in the downstream region under high heat flux density, leading to heat transfer deterioration or even device failure. Some studies have proposed methods such as phase separation structures and electric fields to enhance heat transfer, but these methods have certain limitations when used alone.

[0003] Generally speaking, phase separation structures help to expel gas from the channel and reduce local dryness, but they are often accompanied by a certain loss of heat transfer area. Electric fields can regulate the shape and movement of bubbles, but their enhancement effect is limited under the flow pattern dominated by high aspect ratio bubbles, and it is difficult to maintain the regulation of bubbles in channels with high aspect ratios.

[0004] Therefore, how to enhance bubble control in phase separation heat exchangers has become a key research issue in this field. Summary of the Invention

[0006] This application also proposes a heat exchange method based on the above-mentioned phase separation heat exchange device.

[0007] A phase separation heat exchange apparatus according to a first aspect embodiment of this application includes: Base; A microchannel plate is mounted on the base. The microchannel plate has multiple first and second channels. The first and second channels are spaced apart. A phase separation film is provided between adjacent first and second channels. The widths of the first and second channels are different to generate a pressure difference. The flow direction of the refrigerant in the first channel is opposite to the flow direction of the refrigerant in the second channel. An electric field assembly includes multiple electrode sheets and multiple linear electrodes, wherein the linear electrodes are electrically connected to the electrode sheets, and the linear electrodes extend into the first flow channel and the second flow channel, and the linear electrodes are equidistantly arranged along the length direction of the first flow channel and the second flow channel; A cover plate, which is mounted to the base and covers the microchannel plate; The base is capable of being heated and transferring heat to the microchannel plate.

[0008] The phase separation heat exchange device according to the embodiments of this application has at least the following beneficial effects: the refrigerant in the first flow channel and the second flow channel flows in opposite directions. After the refrigerant is heated, the refrigerant located downstream in the first flow channel evaporates and transfers the bubbles to the upstream of the second flow channel, and the refrigerant located downstream in the second flow channel evaporates and transfers the bubbles to the upstream of the first flow channel, thereby reducing the phenomenon of local drying in the downstream areas of the first and second flow channels; moreover, the linear electrodes are equidistantly arranged along the first and second flow channels, which can independently regulate the refrigerant in the upper, middle and lower reaches of the first and second flow channels, improving the accuracy of regulation.

[0009] According to some embodiments of this application, the base is provided with a first inflow stabilizing cavity, a first outflow stabilizing cavity, a second inflow stabilizing cavity, and a second outflow stabilizing cavity. The two ends of the first flow channel are respectively connected to the first inflow stabilizing cavity and the first outflow stabilizing cavity, and the two ends of the second flow channel are respectively connected to the second inflow stabilizing cavity and the second outflow stabilizing cavity.

[0010] According to some embodiments of this application, an installation groove is provided between the first flow channel and the second flow channel, and the phase separation heat exchange device further includes a fixing plate. The fixing plate has a plurality of equidistant phase separation holes, the phase separation film is fixed to the fixing plate, and the fixing plate is fixed to the installation groove.

[0011] According to some embodiments of this application, the two sides of the phase separation hole are a first phase separation region located in the first flow channel and a second phase separation region located in the second flow channel, respectively, and the width of the first phase separation region is different from the width of the second phase separation region.

[0012] According to some embodiments of this application, the two ends of the linear electrode are connected to the electrode sheet, and the middle part of the linear electrode is disposed in the first flow channel or the second flow channel.

[0013] According to some embodiments of this application, the output voltage of each of the electrode plates can be controlled individually.

[0014] According to some embodiments of this application, both the base and the microchannel plate are provided with temperature measuring holes, and temperature sensors are installed in the temperature measuring holes to monitor the temperature.

[0015] According to some embodiments of this application, both the base and the microchannel plate are provided with pressure measuring holes, and pressure sensors are installed in the pressure measuring holes to monitor pressure.

[0016] According to some embodiments of this application, the phase separation heat exchange device further includes a heater connected to the base to transfer heat, and the heater drives the refrigerant in the first or second flow channel to evaporate.

[0017] The heat exchange method according to a second aspect embodiment of this application, which is based on the above-described phase separation heat exchange device, includes the following steps: The refrigerant enters the first flow channel and the second flow channel, and the refrigerant in the first flow channel flows in the opposite direction to the refrigerant in the second flow channel. An external heat source transfers heat to the first flow channel and the second flow channel through the base; The refrigerant in the first flow channel continuously absorbs heat during the flow process. The refrigerant evaporates and generates bubbles in the downstream region of the first flow channel. The gaseous refrigerant moves to the upstream region of the adjacent second flow channel through the phase separation film, thus avoiding excessive dryness in the downstream region of the first flow channel. The refrigerant in the second flow channel continuously absorbs heat during the flow process. The refrigerant evaporates and generates bubbles in the downstream region of the second flow channel. The gaseous refrigerant moves to the upstream region of the adjacent first flow channel through the phase separation film, thus avoiding excessive dryness in the downstream region of the second flow channel. The electrode sheet outputs voltage to the linear electrode, and the refrigerant is disturbed by the current, which accelerates the intermittent contact between the bubbles and the heated surface. By adjusting the output voltage of the electrode plates arranged along the first and second flow channels, the local current intensity in different regions of the first and second flow channels is changed, thereby enabling more precise regulation of the refrigerant.

[0018] The heat exchange method according to the embodiments of this application has at least the following beneficial effects: by setting up a first flow channel and a second flow channel with opposite flow directions, the drying phenomenon downstream of the first flow channel and the second flow channel can be avoided during gas phase conversion. Moreover, by individually adjusting each electrode plate, the refrigerant in the upper and middle regions of the first flow channel and the second flow channel can be finely controlled, thereby improving the control accuracy.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] With the development of aerospace, chip cooling, fuel cells, and high-power electronic devices, the demand for heat dissipation is rapidly increasing. Although traditional microchannel heat exchangers can improve heat transfer efficiency, they often dry out due to gas phase accumulation in the downstream region under high heat flux density, leading to heat transfer deterioration or even device failure. Some studies have proposed methods such as phase separation structures and electric fields to enhance heat transfer, but these methods have certain limitations when used alone.

[0029] Generally speaking, phase separation structures help to expel gas from the channel and reduce local dryness, but they are often accompanied by a certain loss of heat transfer area. Electric fields can regulate the shape and movement of bubbles, but their enhancement effect is limited under the flow pattern dominated by high aspect ratio bubbles, and it is difficult to maintain the regulation of bubbles in channels with high aspect ratios.

[0030] Therefore, how to enhance bubble control in phase separation heat exchangers has become a key research issue in this field.

[0031] In response, this application proposes a phase separation heat exchange device in which the refrigerant in the first and second flow channels flows in opposite directions. After the refrigerant is heated, the refrigerant downstream of the first flow channel evaporates and transfers bubbles to the upstream of the second flow channel, and the refrigerant downstream of the second flow channel evaporates and transfers bubbles to the upstream of the first flow channel. This reduces the phenomenon of localized drying in the downstream areas of the first and second flow channels. Moreover, the linear electrodes are equidistantly arranged along the first and second flow channels, which allows for independent control of the refrigerant in the upper, middle, and lower reaches of the first and second flow channels, improving the accuracy of control.

[0032] In addition, this application also proposes a heat exchange method based on the above-mentioned phase separation heat exchange device. By setting up a first flow channel and a second flow channel with opposite flow directions, the drying phenomenon in the downstream of the first flow channel and the second flow channel can be avoided during gas phase conversion. Moreover, by adjusting each electrode plate individually, the refrigerant in the upper and middle regions of the first flow channel and the second flow channel can be finely controlled, thereby improving the control accuracy.

[0033] Reference Figure 1 The phase separation heat exchange device in the first aspect embodiment of this application includes a base 100, a microchannel plate 200, an electric field component 300, and a cover plate 400. The base 100 and the microchannel plate 200 together constitute the main structure of the phase separation heat exchange device. The base 100 supports other components of the device and also transfers heat from an external heat source to the microchannel plate 200. The microchannel plate 200 has multiple flow channels for heat exchange, through which a refrigerant flows, absorbing heat from the base 100 and evaporating. The electric field component 300 acts on the refrigerant in the flow channels, changing its evaporation characteristics by introducing an electric current, thus regulating the bubbles. The cover plate 400 seals the flow channels on the microchannel plate 200 to prevent the external environment from affecting the heat exchange process.

[0034] Specifically, the microchannel plate 200 is mounted onto the base 100, as shown in the reference. Figure 2 The microchannel plate 200 has multiple first flow channels 210 and second flow channels 220, which are distributed alternately. (Refer to...) Figure 3A phase separation film 230 is provided between adjacent first flow channels 210 and second flow channels 220. The phase separation film 230 allows the gaseous phase of the refrigerant to pass through while blocking the liquid phase, so that after the refrigerant evaporates, its gaseous phase can pass through the phase separation film 230 to the adjacent flow channel. The specific material and structure of the phase separation film 230 are existing technology and will not be described further here. To facilitate the smooth entry of the gaseous refrigerant into the adjacent flow channels, the widths of the first flow channel 210 and the second flow channel 220 are different to create a pressure difference. This pressure difference drives the gaseous refrigerant to move laterally, allowing it to cross between different flow channels. It is worth noting that the flow direction of the refrigerant in the first flow channel 210 is opposite to that in the second flow channel 220.

[0035] The electric field assembly 300 includes multiple electrode plates 310 and multiple linear electrodes 320. The linear electrodes 320 are electrically connected to the electrode plates 310 and extend into the first flow channel 210 and the second flow channel 220. When the electrode plates 310 are activated and output voltage to the linear electrodes 320, the refrigerant in the first flow channel 210 and the second flow channel 220 changes the growth, detachment, and movement state of bubbles under the action of current, thereby controlling the bubbles. The linear electrodes 320 are equidistantly arranged along the length of the first flow channel 210 and the second flow channel 220, thereby enabling targeted bubble adjustment in different areas of the first flow channel 210 and the second flow channel 220, resulting in higher precision and flexibility.

[0036] The cover plate 400 is installed on the base 100 and covers the microchannel plate 200. The cover plate 400 is provided with an elastic sealing ring, which can improve the sealing performance of the cover plate 400 after installation and reduce the impact of the external environment on the heat exchange process.

[0037] Furthermore, in this embodiment, the cover plate 400 also includes a cover plate body 410 and a transparent plate 420 connected to each other. The cover plate body 410 has a hollow observation window, through which the user can observe the flow of the refrigerant in each channel.

[0038] Furthermore, referring to Figure 4 and Figure 5 An installation groove 240 is provided between the first flow channel 210 and the second flow channel 220. This phase separation heat exchange device also includes a fixing plate 250, on which a plurality of equidistant phase separation holes 251 are provided. The phase separation membrane 230 is fixed to the fixing plate 250, and the fixing plate 250 is fixed to the installation groove 240. Thus, the phase separation membrane 230 is fixed between the first flow channel 210 and the second flow channel 220 by the fixing plate 250.

[0039] Specifically, in this embodiment, two fixing plates 250 are provided, and the phase separation membrane 230 is sandwiched between the two fixing plates 250 to form a phase separation assembly. Limiting grooves 260 are also provided at both ends of the mounting groove 240, and the end of the phase separation assembly can be inserted into the limiting groove 260 for positioning and fixation. When maintenance or replacement of the phase separation membrane 230 is required, the entire phase separation assembly can be removed from the limiting groove 260, and the phase separation membrane 230 can be disassembled.

[0040] Furthermore, regarding the width settings of the first flow channel 210 and the second flow channel 220, in some embodiments, the widths of the first flow channel 210 and the second flow channel 220 gradually change along their length direction. For example, as the refrigerant flows, the widths of both the first flow channel 210 and the second flow channel 220 gradually decrease. Consequently, in the downstream region of the first flow channel 210 and the second flow channel 220, the narrower flow channel width causes the pressure to rise, forcing the bubbles to flow to adjacent flow channels, thereby achieving lateral driving of the gaseous refrigerant.

[0041] In other embodiments, reference is made to Figure 6 The phase separation hole 251 has a first phase separation region located in the first flow channel 210 and a second phase separation region located in the second flow channel 220 on both sides. The inner walls of the first and second phase separation regions are provided with protrusions or pits, causing the widths of the first and second phase separation regions to differ. This results in a sudden change in the width of the first and second flow channels at the phase separation hole 251, creating a pressure difference between the two regions and prompting the bubble to complete its crossing motion. Varying the flow channel width at the phase separation hole 251 allows for more flexible control of the bubble's crossing position and direction.

[0042] Furthermore, referring to Figure 7 The two ends of the linear electrode 320 are connected to the electrode sheet 310, and the middle part of the linear electrode 320 is disposed in the first flow groove 210 or the second flow groove 220, so that the linear electrode 320 can be disposed in the flow groove as much as possible, and the voltage is applied evenly to the cooling medium in the flow groove.

[0043] Furthermore, the output voltage of each electrode 310 can be controlled individually, thereby allowing for fine adjustment of the current in different areas of the flow channel.

[0044] Furthermore, referring to Figure 8The base 100 has a first inlet flow stabilizing cavity 110, a first outlet flow stabilizing cavity 120, a second inlet flow stabilizing cavity 130, and a second outlet flow stabilizing cavity 140. The two ends of the first flow channel 210 are connected to the first inlet flow stabilizing cavity 110 and the first outlet flow stabilizing cavity 120, respectively, and the two ends of the second flow channel 220 are connected to the second inlet flow stabilizing cavity 130 and the second outlet flow stabilizing cavity 140, respectively. The function of the flow stabilizing cavities is to reduce the impact of external liquid supply equipment on the flow channels. During operation, one stream of refrigerant enters through the first inlet flow stabilizing cavity 110, flows through the first flow channel 210 to the first outlet flow stabilizing cavity 120, and then flows outwards; the other stream of refrigerant enters through the second inlet flow stabilizing cavity 130, flows through the second flow channel 220 to the second outlet flow stabilizing cavity 140, and then flows outwards.

[0045] Furthermore, both the base 100 and the microchannel plate 200 are provided with temperature measuring holes 500, and temperature sensors are installed in the temperature measuring holes 500 to monitor the temperature. Specifically, a plurality of friction-feed temperature measuring holes 510 are machined on one side of the microchannel plate 200. These friction-feed temperature measuring holes 510 are equidistantly arranged along the length of the flow channel to measure the local temperature of the flow channel. A plurality of base temperature measuring holes 520 are also provided on the base 100 at positions corresponding to the friction-feed temperature measuring holes 510. By comparing the temperature values ​​of the base temperature measuring holes 520 and the friction-feed temperature measuring holes 510, the heat transfer along the horizontal and vertical directions can be calculated. Optionally, corresponding inlet and outlet temperature measuring holes can also be provided on each flow stabilizing cavity to monitor the temperature of the refrigerant at the inlet and outlet of the flow channel in real time.

[0046] Furthermore, referring to Figure 9 Both the base 100 and the microchannel plate 200 are provided with pressure measuring holes 600, and pressure sensors are installed in the pressure measuring holes 600 to monitor the pressure. Optionally, corresponding inlet and outlet pressure measuring holes can also be set on each flow stabilization chamber to obtain the pressure changes in the flow stabilization chamber in real time.

[0047] Optionally, the phase separation heat exchange device also includes a heater 700, which is connected to the base 100 to transfer heat. The heat in the heater 700 drives the refrigerant in the first flow channel 210 or the second flow channel 220 to evaporate, thereby simulating a heat-generating device and performing a heat dissipation test on the phase separation heat exchange device.

[0048] A heat exchange method according to a second aspect embodiment of this application, based on the above-described phase separation heat exchange device, includes the following steps: S100. The refrigerant enters the first flow channel 210 and the second flow channel 220, and the refrigerant in the first flow channel 210 and the refrigerant in the second flow channel 220 flow in opposite directions; S200. An external heat source transfers heat to the first flow channel 210 and the second flow channel 220 through the base 100, where the refrigerant is heated. S300. The refrigerant in the first flow channel 210 continuously absorbs heat during the flow process. The refrigerant evaporates in the downstream region of the first flow channel 210 to generate bubbles. The gaseous refrigerant moves to the upstream region of the adjacent second flow channel 220 through the phase separation film 230 to avoid excessive dryness in the downstream region of the first flow channel 210. S400. The refrigerant in the second flow channel 220 continuously absorbs heat during the flow process. The refrigerant evaporates in the downstream region of the second flow channel 220 to generate bubbles. The gaseous refrigerant moves to the upstream region of the adjacent first flow channel 210 through the phase separation film 230 to avoid excessive dryness in the downstream region of the second flow channel 220. S500. The electrode plate 310 outputs voltage to the linear electrode 320, and the refrigerant is disturbed by the current, which accelerates the intermittent contact between the bubbles and the heated surface. S600. Adjust the output voltage of the electrode plates 310 arranged along the first flow channel 210 and the second flow channel 220, change the local current intensity in different regions of the first flow channel 210 and the second flow channel 220, and make more precise adjustment of the refrigerant.

[0049] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
